To all whom it may concern:

Be it known, that I, MAXIMn MAssoN, a

subject of the King of GreatBritain, a resident of Schumacher, Province of Ontario,

new and useful Improvements in Rotary Engines,.of which the following is a specification. 7 V

V This invention relates to improvements in rotary engines, and the object of the invention are to provide an engine that'can be reversed, to provide an engine of simpleconstruction and in which the working parts are not liable to go out of repair, to increase the efficiency of the engine, and generally to" adapt the several parts to better perform the functions required of them. 7

With the above and other objects in View, the invention consistessentially of the improved construction particularly described and set forth in the following specification illustrated in the accompanying drawings forming part of the same, and set forth in the appended claims.

In the drawings: v

Figure 1 is a perspective View of the improved rotary engine.

Figure 2 is a longitudinal section through the engine.

Figure 3 is an end View of the engine.

Figure 4 is a cross section taken on the line 4--1 of Figure 2. V

Figure 5 is a crosssection taken on the line 5-5 ofFigure 2. V Figure 6 is a perspective view of the rotor.

Figure 7 is a sectional detail'taken on. the line 77 of Figure 4. V

Figure 8 is a sectional detail taken on the line 8-8 of Figure 7.

Like characters ofreference refer to corresponding parts in the several figures;

Referring to the drawings; A represents the improved rotary engine comprising a casing 10 through which passes the shaft 11. one end of which isoverhung and provided with a belt pulley 12; a

This engine is designed to be reversible and to this end I provide a pair of inlet steam conduits 13 and .1 1 respectively through which steam is delivered to impinge on the vane .dises. Exhaust passageways 15 are provided in the casing and are formed with exhaust conduits 16 at the bottom of the casing.

On the shaft 11 and towards "the centre Specification of Letters Patent. Patented Apr, I I Application filed January 22, 1921. serial No. 439,325. I 1

- thereof, a disc'17 is secured and on the op'po-- site lateral faces of the said disc, discslS are keyed on the shaft, thelast said discs being p ovlded with perlpheral notchesli). Dominion of Canada have invented certain:

Between each .pair of notched discs 17 and 18 .are'located serrated van'ed discs 20 and discs 22 are placed on theshaft'to embrace the said discs already .positioned'in the shaft.

Piston rings .23 are mounted on 'thedisc 17 and form a-steam connection between the said discs and the inner D periphery of the casing 10.

Bolts 21eXtend through the enlarged disc ais'semblyto secure the several discs together to form a rotor, as shown inzFigure 6. The serrated Vaned discs 20 and'21" are constructed with their serrationszoppositely disposed. as shown in Figures 1 and 5, so that such discs will rotate the shaft 11in predetermined but opposite directions, for instance,

the discs 20 will when steam impacts on the vanes thereof, rotatethe rotor in aclockwise direction, and the disc 21 will when steam impacts on the vanes'thereof, rotate the rotor in an anti-clockwise direction.

The serrated disc 20 and its adjacent peripherally notched discs 18 form one unit,

. and vanes 25 are inserted in the'notches 19 in the discs 18 and will engage with the flattened face of the serratlons of the disc 20, and the vanes 25 are normally springpressed outwardly by springs 26 as clearlyshown in Figure 7 The serrated disc 21 and the adjacent peripherally notched discs 18 form a second unit, and vanes 25 are mounted thereon and are normally spring-pressed outwardly by the springs 36,

When this rotary engine is in'use and it is desired to rotate the samem a clockwise;

directionsteam is admitted through the inlet conduit 14 and impinges on the vanes 25 and causes the serrated disc 20 to be ro tated. i

After the steam impacts on the vanes 25' and motion has been transmitted to the rotor, the steam is exhausted through the passage15 to theexhaust conduit 16.

During this. operation steam is notedmitted to the conduit 13. c, When it is found desirable to reverse the engine, steam is out off from the inlet con- 7 duit 14 andsteam is admitted to the conduit 13, so that the steam impacts with the vanes 25 of the serrated disc 21 and transmits ro- V scope of the claims constructed without de-- parting from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is 1.. A reversible rotary engine comprising a casing. a shaft journalled in the casin a D7 pair of oppositely disposed serrated vane-d discs, pairs of notched discs on opposite sides of the serrated discs, outwardly spring pressed vanes fitting in the notches of the second said discs, a pair of discs adjacent the outer notched discs, packing rings engaging the periphery of the last said discs, a pair of larger discs adjacent the last said discs, and means for securing all the discs in assembled position.

2. A reversible rotary engine comprising a iasing, a shaft journalled in the casing, a pair of oppositely disposed serrated vaned discs, pairs of notched discs on opposite sides of the serrated discs, vanes formed with two lateral extensions designed to engage the notches, the body of the vanes being adapted to bear against the facevof the serrations, means on the serrated discs to exert outward pressure against the vanes, a pair of discs adjacent to the outer notched discs, packing rings engaging the periphery of the last said discs, a pair of larger discs adjacent to the last said discs, and means for securing all the discs in assembled position.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
